Automatic Configuration of Vayu Cape at bootup

Following steps can be executed for the first time and it will setup the Vayu-Cape for automatically configuring different functions at bootup.

  • Create a SSH script with all the commands required to configure different functions on Cape such as GPS module reset gpio, 2G/3G modem reset gpio, 2G/3G modem ON/OFF gpio and calling device tree overlays for UART ports.
  • Login as root
cd~
nano boot_run.sh
  • A sample script (boot_run.sh) used by us:
#!/bin/sh -e
/bin/sleep 10
/bin/echo ==============================
/bin/echo 'Setting pins'
/root/bin/pinexp 50						 # GPS MODULE RESET(GPIO 50) is exported			
/root/bin/setout 50 high					 # GPIO 50 is SET HIGH			
/root/bin/pinexp 60						 # MODEM RESET(GPIO 50) is exported to shell
/root/bin/setout 60 high					 # GPIO 60 is SET HIGH
/root/bin/pinexp 45						 # ON/OFF PIN (GPIO 45) is exported
/root/bin/setout 45 high					 # A low level pulse for 4s is applied on ON/OFF(GPIO 45)
                                                                   Pin to turn ON the modem 
/bin/sleep 4
/root/bin/setout 45 low
/bin/sleep 4
/root/bin/setout 45 high
cd /lib/firmware						# Enter device tree kernel
/bin/echo BB-UART1 > /sys/devices/bone_capemgr.9/slots		# Enable UART1 in device tree kernel to communicate
                                                                  with 2G modem
/bin/echo BBB_VAYU > /sys/devices/bone_capemgr.9/slots		
/bin/echo BB-UART4 > /sys/devices/bone_capemgr.9/slots		# Enable UART4 in device kernel to receive NMEA messages 
                                                                  from GPS module 
/bin/stty -F /dev/ttyO4 19200 raw				# Set serial port settings to see NMEA messages
ln -s /dev/ttyO4 /dev/gps1
ln -s /dev/pps1 /dev/gpspps1					 
/bin/echo 'Done with pins and devices'				# Start the NTP server at  boot
/usr/sbin/service ntp restart
/bin/echo 'Already started Ntp'
/bin/echo 'Bringing up dialup'
/usr/bin/pon SERVICE_PROVIDER					# Start the PPPD connection for SERVICE_PROVIDER
/bin/sleep 5							
/sbin/ip route list exact default                               # To get the default gateway
/bin/echo 'All done'
  • Make this file executable. Need to do it only the first time.
chmod +x boot_run.sh
  • Make a crontab entry for this script to start at bootup. 
@reboot /root/boot_run.sh >> /root/boot_run.log

Crontab entry.png

  • In precompiled images uploaded here this script is already present.

Automatic Start of PPP connection at bootup

  • For an always-on connection, most reliable way is to setup pppd as a respawning daemon in init
 http://www.tldp.org/HOWTO/Leased-Line/pppd.html
  • Use wvdialconf and pppconfig to set up your ISP carrier parameters for using wvdial and pppd resepectively.
